Speaking of gadgets that have been usurped by Apple's do-it-all digital dynamos, the new Amazon Kindle 3 ($140/Wi-Fi $190/3G+Wi-Fi) lowers the price of entry while adding new features and removing others. The cheaper model ditches the free, built-in GSM 3G networking for Wi-Fi — the former's still found in the more expensive model — but features a faster six-inch e-ink display with higher contrast, a new graphite color, a new leather cover with integrated LED light, a new "experimental" WebKit-based browser, and double the storage with half the cachet.
